Fedora 27 update: libpng10 Denial Of Service advisory for CVE-2018-13785

The libpng10 package contains an old version of libpng, a library of functions

for creating and manipulating PNG (Portable Network Graphics) image format

files.

This package is needed if you want to run binaries that were linked dynamically

with libpng 1.0.x.

Fix for CVE-2018-13785: the libpng10 library was vulnerable to an integer

overflow and resultant divide-by-zero in the

pngrutil.c:png_check_chunk_length() function. An attacker could exploit this to

cause a denial of service via a crafted PNG file.
